Answer:

The speed of the wave is 156.25 meter per second .

Explanation:

Use the formula for the relation between the speed of a wave and frequency.

v=f \lambda

Where f is frequency and \lambda is wavelength .

f = 125 hz

\lambda=1.25\ meters

Putting all the values in the formula

v=125\times 1.25

v=156.25\ meter\ per second

Therefore the speed of the wave is 156.25 meter per second .

156 is the answer. so 156.25 is almost the same thing, you just round. It's not hard. Thank you!!!

What happens during the apparent retrograde motion of a planet?
anygoal [31]

Answer:

The planet will move from east to west for a couple of months in the night sky.

Explanation:

Retrograde motion is an optical effect due to the fact that Earth rotates more quickly than the planet that apparently has a retrograde motion in the sky.

For example, Saturn has a slower speed in its orbit around the Sun. That means that the Earth will pass it, and that will give the effect that the planet is moving backward. That same scenario can be seen between two cars on a highway, the faster car will see the slower car when it passes as it is moving for a short fragment of time in backward.

Remember that the planets in the night sky move from west to east, in the case of a planet with retrograde motion, it will move from east to west for a couple of months.

). with the input voltage range set at +/- 500mv, what is the smallest difference in voltage that can be resolved? show your cal
dalvyx [7]
The smallest difference in voltage that can be resolved is referred to as the resolution. The resolution can be calculated with the following formula:
resolution=voltage range / digital range
The voltage range in our case is from -500mV to 500mV, which gives 1000mV.
The digital range on the other hand is 2^(number of bits).
It depends on what type of bit board we are using. If the ADC we are using is a 16 bit board, then 2^16=<span>65536.
So, the resolution is:
resolution=1000mV/</span><span>65536=0.015 mV</span>

a plane passes over Point A with a velocity of 8,000 m/s north. Forty seconds later it passes over Point B with a velocity of 10
ValentinkaMS [17]

Acceleration = (change in velocity) / (time for the change)

Change in velocity = (ending velocity) - (starting velocity)

Change in the plane's velocity = (10,000 m/s north) - (8,000 m/s north)

Change in the plane's velocity = 2,000 m/s north

Time for the change = 40 seconds

Acceleration = (2,000 m/s north) / (40 seconds)

<em>Acceleration = 50 m/s² north </em>
